Abstract: A child-resistant dispensing closure consisting of a one-piece molding of resilient material that comprises an inverted cup-shaped cap having a central dispensing opening and a saucer shaped lid that is integrally hinged to the cap at one edge thereof for movement to and from an inverted, closing position closely overlying the cap. The lid has an element which closes the dispensing opening and engages in telescoping relationship therewith. The cap and lid have overlapping catch means for retaining the lid in closing position. The hinge is double acting and provides not only for angular movement to and from the closing position but also for lateral movement of the lid relative to the cap against the resilience of the engaged element and opening for disengaging the catch means.
Abstract: A machine for cleaning debris from railway roadbeds, particularly from between rails of a single track and the space between tracks in railroad yards, comprises an articulated tractor and scraper-loader, each preferably having only two wheels. The scraper-loader has a scraper blade which extends transversely to the track when the machine is in use and a notch which loosely fits over a rail. The blade has wings extending oppositely from the notch. One of the wings has a length which is substantially equal to, but no greater than, the distance between the rails of a track, and the other has a length equal to at least one-half of that distance. The blade has a shoe which overlies the notch and which rides on the surface of a rail to establish the depth of the blade relative to the rails. The shoe is adjustably mounted on the blade so that such depth can be varied in order to clean between the rails of tracks which have rails of different heigths above their ties.
Abstract: A container having a tubular neck and a cup-shaped cap, the container and cap having twist action retaining means such as cooperating threads, in which the container and the cap also have child-resistant locking means. The child-resistant locking means consist of at least one set of co-operating stop and lug, preferably two each. When the cap is turned onto the neck to closed position, that one of the stop or lug on the cap is turned clockwise beyond engagement. The stop has a lug engaging abutment face which is inclined backwardly from its outer edge in a counterclockwise direction. When the cap is turned in retrograde direction toward opening, and the lug engages the abutment face it is urged radially inwardly to more strongly resist unscrewing the cap. The stop and lug are disengageable by radially outwardly deforming the portion of the cap on which one of the stop or lug is formed.
Abstract: A method for folding a newspaper tightly into compacted W-shaped cross-sectional configuration and for retaining the newspaper in that form by mechanical means wrapped around its exterior. A conventionally half-folded newspaper, for example, as produced by a standard printing press, is continuously moved along a path that is perpendicular to the center of the half-fold, folded back upon itself along a quarter-fold line coincident with the path and folded forwardly along eighth-fold lines that are parallel to and on opposite sides of the quarter-fold line and that are equidistant from the quarter-fold line and the lateral edges of the newspaper. The folded newspaper in this "W" configuration is compacted laterally, bringing its folded portions tightly against each other and a retaining element is wrapped around its exterior. The retaining element preferably is a sealed jacket of moisture-proof sheet material which is progressively formed around the compacted newspaper as it continues along the path.
Abstract: An apparatus for compacting refuse as in the body of a rear loader refuse truck having a movable panel which extends across the body as a barrier against which the refuse is compacted by a packer blade. The packer blade is movable through a loading hopper to move the refuse into the rear of the body and to compact it against the panel. The apparatus has an hydraulic system including a pump for supplying fluid at a controlled maximum system pressure, an hydraulic cylinder mechanism for powering the packer blade and a valve which is biased toward neutral and which is manually movable to a power position for supplying fluid to the hydraulic cylinder. The valve has pressure responsive means which hold it in power position and which are deactivated when the pressure in the hydraulic cylinder reaches a level below maximum system pressure.
Abstract: Child-resistant locking means for a container and a cap therefor. The container has a tubular neck and the cap has a circular top and an annular skirt. The container neck and cap have interengageable threads for retaining the cap on the closure. The child-resistant locking means consist of an outwardly extending stop on the container neck and a cap lug engageable therewith to normally prevent retrograde rotation of the cap. The cap lug is located on a curved, resilient, web-like member which extends around the base of the cap and which has outwardly extending struts to space it from the cap. The cap lug is located about 45.degree. from one of the struts. In the preferred embodiment the resilient member is a complete ring, either circular or oval or a similar shape. Squeezing the resilient member inwardly along a diameter spaced about 45.degree. from the cap lug bulges the member outwardly at the lug so that the lug clears the container stop when the cap is rotated for removal.
Abstract: A child-resistant medicine vial, or the like consisting of a container and a cap therefor. The container has a hollow body and a tubular neck and the cap has a disc-like top and two concentric depending skirts. The inner skirt is adapted to be inserted into the open end of the container neck. The container has an outwardly extending annular flange which is spaced below the open end of the neck. The outer cap skirt is relatively flexible and extends telescopingly over the open end of the container, the bottom edge of the skirt reaching down into contact with or at least close to the flange. At least one upwardly extending ramp on the flange is engageable by a lug on the lower margin of the outer cap skirt. When the outer cap skirt is not stressed, the lug lies radially outside of the circular path defined by the ramp.

Abstract: Child-resistant locking means for a container having a threaded neck and a closure therefor. The closure has an inner threaded skirt and an outer more flexible skirt on the lower margin of which there is at least one axially extending, depending lug. The container has an abutment near, but spaced radially from, the base of the neck. The abutment has a face that lies in a radial plane of the container and an outer surface that extends inwardly from the outer edge of the abutment face angularly across the normal circular path of the closure lug. When the closure is turned onto the container neck, the lug (1) engages the outer surface of the lug and is flexed outwardly thereby, (2) snaps inwardly after it is turned beyond the abutment and (3) engages the radial face of the abutment when the closure is turned in a retrograde direction. In order to remove the closure, the outer skirt and the tab manually are squeezed inwardly so as to pass the abutment.
Abstract: A hole cutter for hard material such as ceramic tile. The cutter has a cylindrical body which has an axial opening and a pilot drill is mounted therein. The drill and the opening are non-circular, for example, hexagonal, in order to prevent relative rotation between the drill and the body. The body has a plurality of axially extending recesses in its periphery and an axially extending cutting blade which has an arcuate cross-section is positioned in each recess. The drill and the blades have carbide tips. The tips on the blades have beveled outer corners which prevent them from radially spreading when drilling and which minimize chipping the tile or its glaze. Mounting holes through the blades and in the recesses are spaced circumferentially away from their center lines to prevent improper mounting.

The mechanism also includes an auxiliary pivot bar mounted at the rear of the vehicle bed and a striker mounted at the front edge of the platform which can be moved into extended position in order to engage the pivot bar when desired so that, as the lift arms move to upper position, the platform is swung upwardly relative to the lift arms from horizontal to reach vertical, tailgate position relative to the vehicle bed when the lift arms reach their upper position.
Abstract: A method and apparatus for fabricating continuous lengths of cleated belting. The method includes the steps of feeding a continuous length of belting base material alternately forwardly with or over and backwardly with, a cleat positioning mold first into, then out of and then through the space between vertically moveable press platens. The cleats are assembled with and cured to the base material in longitudinally adjacent groups. Each group of raw cleats and a corresponding section of the base material is moved with the mold forwardly into the press, cured, and then moved rearwardly with the mold out from between the press platens. The cured section is separated from the mold. A new group of uncured cleats is positioned for a succeeding section. The base material, including the cured section, is moved forwardly relative to the mold until the last cured cleat of the group of cured cleats is positioned at the first of the cleat positions of the mold.
